Well, my friends and I were extremely bored at his house, so we started to explore a bit. We found a Riddler cape, a Batman mask, and an Ichigo sword. With us, you can only expect weirdness to come.

And that it did.

We're such idiots.

None of this was scripted. This came out of the top of our heads.
